CALCIUM SIGNALING

Calcium plays an important role in cell signaling, either by direct signal transduction or acting as a second-messenger. Calcium signaling regulates a large range of physiological cell functions and processes such as motility, cell proliferation & apoptosis, excitability & depolarization, exocytosis & synaptic plasticity. In addition, movements of calcium ions that result in membrane potential changes are particularly important in heart function and neuronal transmission.
